Embodiment approach

[0184] 1. Using CNN network as the semantic representation module:

[0185] Such as Figure 8 As shown in , it is a framework diagram of a decision-making model including a convolutional neural network-based semantic representation module proposed by an embodiment of the present invention. In natural language processing, compared with the convolution operation of images, the text matrix can be regarded as an image, and then a convolution operation can be performed on it using a filter. Language-based representations have structural constraints inherent in order, representing each row in the text matrix as a word. The convolution operation can be performed using a filter whose "width" is the dimension d of the word vector. In addition, different types of filters can be obtained by changing the "height" of the filter for processing text information containing different numbers of words, and the height of the filter is called the window size of the filter.

Abstract

The invention provides a decision making method and apparatus based on survey data, a storage medium and a terminal device. The method comprises the following steps: obtaining survey data, wherein thesurvey data comprise a continuous value feature, a category feature and text information for describing a survey process; extracting a semantic representation feature from the text information; combining the continuous value feature with the category feature to obtain a width model input feature; performing generalization processing on the preprocessed continuous value feature and the category feature to obtain a depth model input feature; and inputting the semantic representation feature, the width model input feature and the depth model input feature in a decision making model to obtain a decision making result of the survey data. By adoption of the decision making method and apparatus provided by the invention, the decision can be made by combining the semantic features of the text inthe survey data, which is beneficial to improving the accuracy of the decision making.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a decision-making method, device, storage medium and terminal equipment based on survey data. Background technique [0002] Internet finance is an emerging financial business that integrates traditional finance and Internet technology, and relies on new technologies such as big data, cloud computing, and artificial intelligence to realize financial integration, payment, and information intermediary services. With the rapid expansion of Internet financial services and the continuous emergence of financial innovation products, Internet finance has exposed a large number of risks, mainly including: credit default and fraud risks, consumer rights infringement risks, and capital flow risks. Therefore, how to use risk control to solve the risks faced by Internet finance and reduce the losses of users and enterprises is a problem that financial enterprises need to solve urgent...
